MINI ANALOG SERIES
CMOS SINGLE WIDE-BAND OPERATIONAL AMPLIFIER S-89402A/89403A Series
Seiko Instruments Inc. 1
The mini analog series is a group of ICs that incorporate a
general-purpose analog circuit in an ultra-small package.
The S-89402A and S-89403A series are CMOS type wide-band
operational amplifiers with a 10 MHz gain-bandwidth product
(GBP) and can be used in a negative feedback circuit with five
times or more gain. Since these products can be driven at a
lower voltage with lower current consumption than existing
bipolar operational amplifiers, they are ideal for use in small
battery-powered portable equipment.
Features
• Gain-bandwidth product: 10 MHz (typ.)
• Bandwidth: 1 MHz (typ.) @ Gain = 10
• Used with a gain of five or more
• Can be driven at lower voltage than existing general-purpose
operational amplifiers: VDD = 2.7 to 5.5 V (S-89402A)
VDD = 1.2 to 3.3 V (S-89403A)
• Low current consumption: IDD = 1.9 mA (typ.) @ 3.0 V
• Current consumption in shutdown mode: IDD = 0.1 µA (typ.)
• Wide I/O voltage range: VCMR = VSS to VDD
• Large output current
• Low input offset voltage (5.0 mV max.)
• Small package (SOT-23-6: 2.9 mm × 2.8 mm)
Package
• 6-Pin SOT-23-6 (package drawing code: MP006-A)
